when i try and run boot defrag I get this; Some registry entries were missing from the boot optimization section of the registry. (0x89000017) as far as i know all keys seem to be in place @ HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg & HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Prefetcher all i've done is uninstalled perfectdisk recently. does anyone know what entries are missing? also the prefetcher folder is missing the layout.ini and my boot speed is slow. I ran the process idle tasks command but the process didn't start.
